The "Schmutzfink" by Riesel Design is a mudguard for saddles designed for children's bicycles. The cutouts for mounting on the saddle rails are designed so that the mudguard can be attached to smaller children's saddles, as the saddle rails are closer together at the back. The function of the "Schmutzfink" corresponds to the mudguard "Ritze L". A secure and firm hold on the saddle is ensured through four attachment points. Installation is tool-free. The "Schmutzfink" was designed as a splash guard to protect the rider's rear from dirt, mud, and water under adverse conditions. The shape of the mudguard has been specifically developed and optimized to meet the requirements of modern frames for children's saddles. Special colors for the graphics and an additional coating provide lasting protection against harsh conditions.
